A Application inea Apers, ist?. seri-.11 nu. 233,126. rno'moael.)

T0 all whom it may concern:

Be it known' that I, JUSTUS B. ENCLZ, of the city, county, and State ofNew York, have in vented new and useful Improvements in ElectricGas-Lighters, of which the following is a full, clear, and exactdescription.

My invention has reference to that class of burners in which the gas isautomatically turned on and a spark produced at the burnertip to ignitethe same on closing the lightingcircuit, and on closing theextinguishing-circuit the gas is turned off.

The invention has for its object to provide new and useful improvementsin this style of burner, whereby it is rendered more compact, efficient,and economical; and to this end the inventionconsists in certain novelfeatures of construction and combinations of parts,hereinafterfullydescribed,andparticularlypointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

yFigure l is an enlarged vertical sectional view of an electricgas-lighter embodying my improvements. Fig. 2 is a plan view of thesame; and Fig. 3 is a sectional plan view ou the line x x, Fig. 1.

The threaded metal couplingsleeve tliebase of the burner is adapted tobe screwed on the gaspipe, as usual, and is formed with the wide annularflange B. To the sleeve A, around its inner edge, is secured the uprighttubular shell G, preferably of thin metal, the upper end of which isscrewed into a recessed disk, D, forming agas-tight joint.

The disk D is formed with a wide annular flange, E, corresponding insize and parallel with that on the lower coupling-sleeve, A, and isformed with au external thread, on which is vscrewed downto the flangeE, to form a gaslower electromagnetic coil, J. The two elec- Y tromagnetic coils are insulated from each other by a collar, K, ofnon-conducting material, surrounding the shell C, extend out flush withthe outer edges of the upper and lowerv l is thus surrounded by theupper portion of the upper electro-magnetic coil, I, and forms itscore-section.

The disk D is formed with a central depression, M, forming a seat forthev valve N, and

the piece M with a vertical aperture, M, leading downward therefrom, inwhich plays the stemN of the valve. somewhat larger than thevalve-stem,.in order The aperture M2 is made to provide a passage forthe gas to the burnertube G and tip I-I when the valve is open.

To the lower end of the valve-stem N is attached a soft-iron cylindricalblock, O, whichl is somewhat smaller than the interior of the shell C,to leave a passage for the gas, and is adapted to move verticallytherein with the valve when acted upon as an armature by the upperelectro-magnet, composed of the coil I and core-section M. i

Within the upper part ofthe lower coil, J,

also is xed a soft-iron core-section, P, having a central verticalpassage, P, for the gas and formed with a vertical side slot, P2, inthey lower end of which is pivoted a lug on the swinging soft-iron blockor armature P3. Said lug is prolonged toform a dog, Pt, which isreceived loosely in a side slot, O', in the, upper movable armature, O,and is adapted to automatically engage a shoulder, O2, formed at theinner side of the slot O' by the weight of the attached armature P3 whenthe armature O is raised by the action of the upper l magnet.

Two binding-posts, Q B, are arranged on the top ange, E, and areinsulated therefrom in anysuitable manner. The post Q is oonnectedwithvone terminal of the upper coil, I,

and the post R by an insulated conductor, R',

ruiming downward within the outer casing, L, with one terminal of thelower coil, J. The other terminalof the upper coil, I, is connected byan insulated conductor, I', with the fixed-contact S of thespark-producer, which contact is supported on, while insulated from, thecap F in any suitable manner.

The movable contact S is of the usual de IOO seription, and is incontinuous electric connection with the ground through its holdingspringS2 or its guide-tube, the cap F, shell C, sleeve A, and through thegas-pipe on which the same is held. vThe other terminal of the lowercoil, J, is grounded through the sleeve A in like manner.

- To the binding-posts Q R are connected wires T V, respectively,leading to the two contacts ot' a suitable switch, W, whichin turn isconnected with one pole of a battery, U, the other pole of which issuitably grounded. With this arrangement, when the gas is'to be lighted,the switch Wis turned to connect the upper coil, I, through thebinding-post Q and wire T, with the battery. An earth-circuit is thusmade from the battery through connecting-wire to switch W, through wireT, post Q, upper coil, I, wire I', contacts S and S', thence totheground, as described, and back to the battery. The upper electro-magnetbeing thus active, the armature O is raised, opening the valve N andpermitting the gas to flow from the burner-tip, and is prevented fromfalling back by the engagement of the swinging dog P* with the shoulderO2, thus keeping the valve open.V The armature Oat the same time isdrawn up to the fixed coreseetion M, when its valveN, or a projectionthereon, strikes the holding-spring S, thereby raising the movablecontact S', breaking the circuit, and producing a spark which ignitesthe gas. When the circuit is thus broken, however, the upper magnetbecomes inactive, allowing the armature O to fall with the valve untilchecked by the dog Pf and the circuit is again closed. This operation isrepeated, producing a succession of sparks, until the gas is ignited,when the switch W is turned to break the circuit. l

To extinguish the light, the circuit is closed by the switch through thelower coil and connections. The lower magnet, then becoming active,quickly raises the swinging armature I?3 into contact with thecore-section I?, disengaging the dog P from the shoulder O2 on thearmature O, allowing the same to fall by gravity, aided by theattraction of the lower mag+ net, and close the supply-regulating valve.The tubular shell C, in connection with the core-sections M P, reallyforms a continuous hollow or chambered core for both magnets,V and ismade separate from'the core-sections only as a matter of convenience inmanufacture. For the same reason it may be made of a different metaltherefrom, it having no appreciable eiiect upon the magnets, owing toits thinness. By thus winding the coils upon a hollow core within whichthe valve-operating devices are Vlocated an extremely simple and compactburner is produced at a low cost..

Having thus fully described my invention, what I claim as new, anddesire tovsecurc by Letters Patent, is v 1. The combination, with thesleeve having the upper and lower coresections, the electromagneticcoils surrounding the same, and the valve and its operating-armature, ofa second armature pivoted to swing within the core, and a dog forengaging the valve-operating armature operated by the swinging armature,substantially as shown and described.

2.. The combination,with the pipe-coupling sleeve, the hollow shell, theanuularly-flanged disk on the upper end of the sleeve, having a centralopening forming a valve-seat, and carrying the binding-posts, theelectro-magnetic coils surrounding the sleeve, a valve closing the valveopening and provided with a stem extending down into the sleeve, and thevalveoperating devices within the sleeve, of the cap upon the disksupporting the burner-tube, the

insulated fixed contact extending adjacent to the burner-tube, thelvertically-movable contact extending into the cap, and asupportingspring for said movable contact in the path of the said valve,substantially as set forth.

3. The combination, with the sleeve, the upper and lower core-sections,the electromagnetic coils surroundng said sleeve, the upward-openingvalve, and the verticallymovable armature for operating it, of a secondarmature movable within the core and pro-
